Description

Technical Field

[0001] The utility model relates to the technical field of natural gas burners, in particular to a natural gas burner with a temperature insulation protection structure. Background Art

[0002] Artificial boards, also known as synthetic boards and composite boards, are a kind of building material processed from wood or other fiber materials. Artificial boards are widely used and are often used in furniture manufacturing, interior decoration, building structures, packaging, etc.

[0003] When artificial boards are produced and processed, pulping is generally carried out first, which is to soak the raw materials in water and break them into fibers by mechanical or chemical methods. The fibers produced in the pulping process need to be separated and cleaned to improve the fiber quality. Then it is pressed, that is, the pulp is sent to a hot press to solidify it into the shape of a board under high temperature and high pressure. Then the hot-pressed board needs to be placed in a cooling tower for cooling, and then taken out for drying. Then it will be cut according to the designed size, and finally the surface will be sanded, veneered and packaged.

[0004] The above-mentioned drying device for the hot-pressed artificial board generally uses a natural gas burner for drying. The natural gas burner is a combustion device that uses natural gas as fuel. Its working principle is to use natural gas mixed with air, ignite it in the combustion chamber to generate heat, and then heat the inner cavity of the drying box through a heat transfer pipe, so as to achieve the drying of the cooled artificial board in the drying box.

[0005] The existing natural gas burner used for drying the cooled artificial board has a heat transfer pipe which is generally connected to the interface of the drying box through a flange plate. Since the heat transfer pipe itself is a slender tube, heat will be dissipated during heat transfer. Moreover, the heat transfer pipe of the slender tube itself has a low impact protection strength. In addition, the connection structure between the flange plate on the heat transfer pipe and the drying box is less stable.

[0006] The above problems are widespread and urgently need to be improved. Utility Model Content

The burner body 1 is a commonly used natural gas burner, which is a prior art. Some existing structures are not drawn and marked, and there is no need to repeat them.

[0028] In detail, there are four base screws 12 , which pass through the machine base 11 and are threadedly connected to the fixing surface 2 , thereby improving the installation stability of the combustion machine body 1 .

[0029] Furthermore, the insulation jacket 41 is evenly arranged along the outer wall surface of the heat transfer pipe 4. The insulation jacket 41 is made of aluminum silicate fiber cotton. The side section of the insulation jacket 41 is a ring-shaped structure and the thickness is thirty millimeters. The aluminum silicate fiber cotton material has excellent thermal insulation properties, which can prevent the heat generated by the burner body 1 from dissipating during the process of being input into the drying box 3 through the heat transfer pipe 4. It is corrosion-resistant and durable.

[0030] Furthermore, the flange plate 6 is fixedly welded to the left end of the heat transfer pipe 4 , and the pipe sheath 7 is sleeved on the outer wall of the heat transfer pipe 4 , which further improves the protection of the left end connection part of the heat transfer pipe 4 .

[0031] In more detail, the impact-resistant protective layer 5 is arranged along the outer wall surface of the thermal insulation sleeve 41. The impact-resistant protective layer 5 is made of glass fiber reinforced plastic FRP. The side section of the impact-resistant protective layer 5 is a ring-shaped structure and the thickness is fifty millimeters. The glass fiber reinforced plastic FRP material has excellent impact resistance and deformation resistance, which can prevent the heat transfer pipe 4 from being deformed by external impact and affecting the normal heat transfer.

[0032] In general, the flange plate 6 is a square structure as a whole, and there are four symmetrically arranged mounting bolts 61. The mounting bolts 61 pass through the flange plate 6 and are threadedly connected to the side wall of the drying box 3.

This is the existing technology.

[0035] By setting the insulating sleeve layer 41 structure on the outer tube wall of the heat transfer pipe 4, the heat generated by the burner body 1 is effectively prevented from dissipating during the process of being input into the drying box 3 through the heat transfer pipe 4, thereby ensuring the effective utilization rate of heat, and further improving the heat transfer pipe 4 to use all the heat to dry the artificial board in the drying box 3 after preset cooling.

[0036] Moreover, by providing the impact-resistant protective layer 5 structure on the outside of the heat transfer pipe 4, the impact-resistant protection strength of the heat transfer pipe 4 structure itself is greatly improved, thereby preventing the heat transfer pipe 4 from being deformed by external impact and affecting the normal heat transfer.

[0037] In addition, by arranging a pipe jacket 7 on the flange plate 6 and arranging a main reinforcing rib plate 8 structure with secondary reinforcing columns 81 between the flange plate 6 and the pipe jacket 7, the overall stability of the connection structure between the flange plate 6 on the heat transfer pipe 4 and the drying box 3 is improved.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
